Taylor Swift has taken out a restraining order against an obsessed fan who believes he is married to the country music star.

The 24-year-old singer was forced to seek legal protection from the man, named Timothy Sweet, after receiving dozens of emails, letters and social media posts in which he declared his love for the singer.

Mr Smart, 33, even promised to ''Kill'' anybody who stood in the way of their relationship including America's Secretary of State, John Kerry and Taylor's family, and threatened to use a gun to protect the star.

In one disturbing messages to Taylor, My Sweet wrote: ''If anyone in Taylor's family get killed it is not my fault.

Whilst another stated: ''My wife Taylor Swift (Sweet) and I live in Beverley Hills. I am in love with her. In conclusion, we treat each other with dignity and respect. I will carry a gun to protect her the rest of my life. (sic).''

He continued: ''Dearest Taylor, I'll kill any man who gets in the way of our marriage. Message to John Kerry, Secretary of State. Message from YOUR presidential candidate (sic).''

In response to Mr Sweet's actions, Taylor said that his behaviour is ''seriously alarming and harassing'' and the constant messages and phone calls are ''extremely distressing to me and my family''.

She maintains that she does ''not have desire to interact with or communicate in any way with Mr Sweet.''

Following the 'I knew You Were Trouble' singer's legal action, a judge at Los Angeles Superior Court granted her a temporary restraining order which is set to expire on March 25.

Mr Sweet has been ordered to stay at least 100 yards from Taylor, her mother Andrea, father Scott and younger brother, Austin.
